Dateline's A Cool Desert Morning: Susan Winters' murder case explored

According to multiple sources, Nevada attorney Susan Winters died unexpectedly in 2015, and her husband, Dr. Gregory Brent Dennis, told police that she committed suicide by drinking antifreeze, a poisonous chemical.

Gregory also claimed that before her death, Susan had searched on the internet for questions like "How does antifreeze work?" Susan was reportedly found to have amounts of antifreeze and oxycodone (a strong painkiller) in her body.

During the investigation, several things came to light that completely changed the case. The most important fact was that the last internet search was done at 5:15 am, but at that time, Susan was already unconscious and had a lethal amount of antifreeze and OxyCONTIN (a powerful painkiller) in her body, as per the People.

This proved the internet search was not done by Susan Winters, but by someone else. Reportedly, at the time of the Google search, Susan was already unconscious, and her body was in a corpse-like state.

As per multiple sources, the investigation found that Susan's husband, Brent Dennis, was struggling with a cocaine addiction and was also facing a severe financial situation.

Reportedly, he had no money left, and his wife had an insurance policy that could have provided Brent with a sum of $2 million in case of her death.

Brent Dennis sentenced in wife's death, eligible for parole in 2025

According to multiple sources, in 2017, Dr. Gregory was arrested for the murder of his wife, Susan Winters. However, he entered an Alford plea (in which the accused does not admit he committed the crime but admits the prosecution has enough evidence to convict him) and pleaded guilty to voluntary manslaughter.

As mentioned in the Las Vegas Sun, defense attorney Richard Schonfeld said:

"Brent Dennis resolved this case without making any admission of guilt in order to eventually return his life to normalcy."

As per the reports, the trial was postponed multiple times due to the COVID-19 pandemic. However, Brent was eventually sentenced to 3 to 10 years in prison in May 2022.

According to Court TV, he is currently serving his sentence at the Southern Desert Correctional Center in Indian Springs, Nevada, and is eligible for parole beginning May 4, 2025.

To find out more about this case, watch Dateline: A Cool Desert Morning, airing tonight at 9 PM EST, only on NBC.
